Quantitative Aptitude Quiz for SBI Clerk Exam: 07th June 2018

Dear students,

Numerical Ability for SBI Clerk Prelims 2018

Today is the Day 47 of the SBI Clerk 60 Days Study Plan. Numerical Ability Section has given heebie-jeebies to the aspirants when they appear for a banking examination. As the level of every other section is only getting complex and convoluted, there is no doubt that this section, too, makes your blood run cold. The questions asked in this section are calculative and very time-consuming. But once dealt with proper strategy, speed, and accuracy, this section can get you the maximum marks in the examination. Following is the Numerical Ability quiz to help you practice with the best of latest pattern questions.

Q1. Speed of a boat in still water is 8 km/h. If time taken by boat to cover a distance of 18 km upstream and 18 km downstream together is 6 hours. Find the speed of water current.
(a) 4 km/h

(a) 2 : 1
(b) 3 : 1
(c) 4 : 1
(d) 3 : 2
(e) 5 : 2Q3. Time taken by a boat to cover upstream distance is 4 hours more than that to cover downstream distance between two points A and B. If speed of boat in still water is 6 km/h and speed of current is 2 km/h, find distance between A and B.
